DRIVING BOX FOB LOCOMOTIVES- F Application fil ed May 13,1924. Serial No. 713,016 r I To all whom it may concern:

Be it known that I, JOHN L. RoAoH, a citizen of the United States, residing inthe city and county of Childress and State'ot Texas, have invented certain new and useful Improvements in Driving Boxes for Locomotives, of which the following is a specification.

This invention relates to a driving box for locomotives and has for its object to provide a box of such class, in a manner as hereinafter set forthywithmeans'whereby the wear resisting liners will extend be low the horizontal center line of the journal or axle, thus increasingthe wearing surface and eliminating thev tendency to'lift the driving box on the journal when in operation.

A further object of the invention is to provide, in a manner as hereinafter set forth, a driving box having its body por tion formed of two sections permitting of making adjustments forrwear between the journal and driving box liners by adjusting the. pedestal wedge, thus eliminating the necessity of removing the driving wheels for repair. 7 'A further object of the invention is to provide, in a manner as hereinafter set forth, a driving box so constructed whereby the liability of heating the journal and the loosening of the driving box liners is reduced to a minimum, due to the fact thatthe pressure between the'journal and the liners can berelieved by -}proper adjustment of the pedestal wedge. l Further objects of the invention are to provide, in a manner as hereinafter set forth, a sectional driving boxfor locomotives, which is simple in its construction and arrangement, strong compact, durable, thoroughly efficient in its use,lreadily installed, and comparatively inexpensiver With the foregoingand other objects in view, the invention consists of the novel construction, combination andarrangement of parts, as hereinafter more specifioiall-y described and illustratedin the accompanying drawings, wherein is showrian embodiment of the invention, but it is to be understood thatchange's,' variations and modifications can be resorted to which come within the scope of the claims hereunto appended," l

' In the drawings wherein like reference in Figure 1.

characters denote corresponding parts 7 throughout the. several views p Figure 1 is a sectional elevation of a plriving box injaccordance with this invenion. V Figure 2 is a top plan view thereof.

. Figure 3 is alongitudinal sectional view of the driving spring saddle support.

Flgure 4 is an end view of the support. Figure 5 is a perspective view of a closure strip employed in connection with the liners. The body portion of the driving box,

which is substantially of inverted U-shape is indicated generally at 1, and is formed wit-h two oppositely disposed inverted sub stantially L-shapedsections 2, 3, of like construction and having the upper portions extending towards and in--;close proximity to eachother.'

Each of said "sections has a portion of its inner face of arcuate curvature to provide 7 a seat 4, for a liner 5. The seat4 extends from a point in close proximity to theinner upper edge'of the section and terminates at a point removed from the lower end thereof, but below the'horizont al center thereof. The length of each of the seats is such as to extend below the horizontal center line of the journal 6, indicated in dotted lines The inner terminus of the upper portion of each of said sections hasprojecting from the inner face thereof, a transversely extending vertically disposed rib 7, havingits outer face flush with the inner edge of the upper portion of the section. The upper end of the seat 4 merges into theinner side of the'rib 7 At the lowerterminus of the seat 4 each section is provided with an inwardlyprojecting and upwardlyinclined transversely extending lug 8. f f .7

The liner 5, which is segmental in com tour, is of a length toextend from the inner edge of the upper portion of-the section to the lug 8, and the liner iscut away, as at 9, to seat against the lower and inner side'edge of'the rib'7. The-upper edge of the liner 5 I is flush with the outer side edge of the rib 7. The liner 5 is mounted against the seat'4, abuts against the inner side; edge of the rib {and is supported on the upper side of the lug 8. The liner 5 gradually decreases in thickness from the cut-out portion 9 to its lowered e, and said "liner 5 at its lower edge ilS'Of; a width to slightly' project beyond fthev lug ,8.

The upper edge of the liner 5 is formed with Each of the sections with side flanges 11 and 12, which project:upwardly-- and laterally but terminate ata point re-- moved from the loweren'dof tlie s'ectioni The upper face of each section between the flanges 11 and'IQ; iso'f ai'cuate curvature; as indicated at 1 81. and the upper face of one section is a continuation of the are of the upper face oi the other section. The upper face of each section of the, box 1. is provided with a pair of transversely extending sp'aced when and The web 15 is apertured as at16 and hasits outer face" flush with the" vertical portion or the section. The web 145 is spaced 'a substantial distance from the web 15. g

The webs 14: of the sections, when these latter are arranged in coacting relation to set up the body portionot the box, provide in connection with the uppei' faces of the sections, a-pocket 17'. The inner faces of the flanges 11 aridlQ, inwardly with respect' 'to the webs -l4faiec'ut out, as at 18'. thus form'- ing the ends of the pocket 17. Theside walls of the 'poc-ket 17 are provided "by the webs lj la'rid the end walls by the flanges ll and 12, clearly shown in Figure 2. The pocket 17 is provided tor-the reception or a supportfforthe driving; spring saddleyand said support consists of agreetangular block l9,ghaving its lower face 20 conforming iii contour to the shape of the bottom of Vthe 'pocket 17;. The block 19' is of less height than the height of the webs 14, and said block 19 at each end the staff is grooved, as at 21, and which connection with the flanges lland '12 3rovides'the sup"- port 19 with transverselyextending cavities havingeach end positioned in pro iinit'y to aside ofthe block and which are 'adapted tov receive the driving spring s'zldle. Whenth sections 2; 3, inop'p'osedi relation, thesp'ace 22b'etwee'n tlileopposed in? net ends'of the upper-portions of 's aid sec tions,-is closed by astrip 23; which is Hi ount ed in the opposed grooves 10 ot th liner-s5 and sai d strip prevents lubricant fronrbei 'ng c ied t'o th etop-oif the driving"box.

l It' is to be understt'iod howerer thatthe driving bo'X' will be'fitted with pedestal shoes wedges; as welt with drivingbox cellar, such parts re not shown asthey forr'n no part of the invention." i A, bofi constructed in; the manner as stated, "that is having its' 'body: portion fcrin' d' tr two sections; per naits at extending wearliners below the horizontal center-line ot the-journal," thus increasing wearing surface" andeliminating the ten-e assay fie lift the driving box on the-j ouilinal when in operation. The sectional constructior'i, also permits of ina liiiigitdjustliie'nts for wear between the journal and the driving box liners by adjusting the pedestal wedge,

thus feliininating; ;the necessity of removing the driving wheels ior repairs. A box constructedginiai manner as stated furthermore reduces liability of the heating of the journal'and the loosening of the liners in the box by relieving pressure between the journal and the liners and which canbe accent plislied by proper 'adjusttiientotthe pedestal wedgej g It thought that the inany'advantages of a driving box, in accordancewith this in} venti'on, can be readily understood, and al longitudinally disposed rib and lug spaced from each other, the outer side of eachvof saidribs forininga continuation oftihe-inner end edgeofa section saidzlugs arranged below the horizontal center: line of a journal, and oppositely disposed linersdseated" on said lugs and-abutting against the inner sides of and further overlapping said ribs, the upper'endedges of said liners opposing eachother and flush throughout with the inner end edges or" said sections.
